Apply a Noise Gate to Your Life

Lifehack: "Chances are you’ve heard — or rather, not heard — the effects of a noise gate, but unless you’re into audio engineering, you probably didn’t realize it. Ever been at a concert or listen to a radio broadcast where it sounds great when there’s music playing or a voice speaking, but no hiss in the pauses between? Unless the signal happens to be really clean, odds are that was a noise gate at work, removing the hiss while letting the loud parts shine through."
